2nd overflow box

[vsnsofadrgn]

it seems the overflow box i have cant keep up with the pump, so i am considering getting a 2nd overflow box. ive got a ball vavle on the return line, but it still seems to be too much. any other suggestions?

As long as you have around 6-10 times tank turnover in the sump I wouldn't add another overflow and just restrict your ball valve more or even better T off the return to go back to the sump so you don't put back pressure on the pump.

Are the bubbles under control now?

thats the thing, i feel like i dont have the flow i was after. maybe im just not used to this type, lol, but i thought it would be much stronger.

the air bubbles are gone and its SILENT! .

t ing off the return line sounds much cheaper than a 2nd overflwo box, LOL, how do i do that?

Actually I wouldn't recommend too much flow through the sump mostly because of noise issues. Even if it's only 300 GPH that is sufficient.

I know you use clear tubing instead of PVC but the concept is the same as below, get a Hose-Locking Tee Connector and yet another ball valve to control flow back to the sump and you're set.

i would love to have a refugium, but my lil 10 doesnt have room and i cant fit anything else under there. we are however goin to build a new stand someday, so i could make a 20 gal fit in there.

the only other thing i could do is put the protien skimmer on as a hot in the sump. that would give me the room. ive already got a ball valve, so all id need is the tubing and the t. thats cheap. hehe.

guess ill have to play with it. thanks for your help.
